Resource Category Tonnes Grade Li[2]O LCE (Mt) (Li[2]O%) (t) (t)

Indicated 21.6 1.12 241,000 597,000

Keith D. Phillips, President and Chief Executive Officer, commented: "Increasing the scale of our North Carolina mineral resource to 39.2 Mt at 1.09% Li2O establishes our asset as one of the largest spodumene resources in North America - and the only one in the United States. The expanded resource offers the potential for increased annual lithium production, something we will evaluate as we prepare our updated Scoping Study for release next month. All this is coming together at an ideal time, as the public and private sectors dramatically increase their investment in the electrification of America. Given the scope and strategic location of our Piedmont Lithium Project, we believe we are ideally positioned to play a critical role in helping the United States build a clean energy economy and a U.S. based EV supply chain."
